  1. A population study of the effect of carbon black nanomaterial on erythrocyte shape. The average values of the portion of discocytes (D), echinocytes (E) and stomatocytes (S) are given after 1 hour, 3 hours and 24 hours of incubation with the carbon black nanomaterial (test sample) and with citrated and phosphate buffered saline (control sample). SD: standard deviation. p: statistical significance of the difference between the average values of the test and control, calculated by the t-test. P: statistical power. NA: non applicable as there were les than 1% of stomatocytes in all samples. Altogether 10712 cells were included in the analysis.
